Objective To examine the expression of IgA1 and B1a positive cells in palatine tonsils of IgA nephropathy (IgAN) patients, and to analyze the association between B1a cells and clinicopathological changes. Methods Eight patients diagnosed as IgAN by renal biopsy and 8 chronic tonsillitis patients without nephritis as control were enrolled in the study.Immunofluorescence and laser scanning confocal microscope (LSCM) were applied to observe the localization and quantitative calculation of Bla and IgA1 positive cells. Statistic analysis of the association of B1a cells with proteinuria and pathological Lee's grading was performed. Results Bla cells were mainly localized in germinal center of tonsil, and IgA1 positive cells were mainly localized in subepithelium of tonsil. Compared to control group, the percent of B1a cells and IgA1 positive cells was significantly higher in IgAN (P<0.01). There was a positive correlation between Bla cells and IgA1 cells (P<0.05). In IgAN, the percent of B1a cells in patients with hematuria and proteinuria was obviously higher than that of patients with hematuria only (P<0.05). The number of Bla cells in IgAN patients with≥Lee's grade Ⅲ was significantly higher than that of those < grade Ⅲ (P<0.05). Conclusions IgA1 may be secreted by Bla cells in the tonsil of IgAN patients. The number of B1a cells is correlated with exacerbation of proteinuria and pathological severity, which may play an important role in pathogenesis of IgAN.

Referring to the rules for agricultural seed testing (GB /T 3543-1995) issued by China, the test of sampling, seed purity, weight per 1 000 seeds, seed moisture, seed viability and germination rate had been studied for screening seed quality test methods of Pesudostellaria heterophylla. The seed quality from different collection areas was measured. The results showed that at least 6.5 g seeds should be sampled and passed through 10-mesh sieve for purity analysis. The weight of 1 000 seeds was determined by using the 500-seed method. The phenotypic observation and size measurement were used for authenticity testing. The seed moisture was determined under the higher temperature (130 ± 2) degrees C for 5 hours. The seeds were dipped into 0.2% TTC sustaining 1 hour at 40 degrees C, then the viability could be determined. The break dormancy seeds were cultured on sand at 10 degrees C. K cluster analysis was applied for the data analysis, the seed quality from different collection areas grading of P. Heterophylla was described as three grades. The seed quality of each grade should reach following requirements: for first grade seeds, germination rate ≥ 86%, 1 000-grain weight ≥ 2.59 g, purity ≥ 87%, moisture ≤ 13.1%; for second grade seeds, germination rate ≥ 70%, 1 000-grain weight ≥ 2.40 g, purity ≥ 77%, moisture ≤ 14.3%; for third grade seeds, germination rate ≥ 41%, 1 000-grain weight ≥ 2.29 g, purity ≥ 76%, moisture ≤ 15.8%. The seed testing methods for quality items of P. heterophylla had been initially established, as well as the primary P. heterophylla seed quality classification standard.

Objective To investigate the clinical characteristics of posterior malleolar ankle fracture, and the selection of the surgical approach. Methods From January 2013 to September 2015, 83 cases of posterior malleolar fractures were retrospectively analyzed. Haraguchi typing was performed based on the three-dimensional CT. There were 54 cases with HaraguchiⅠtype, 16 cases with HaraguchiⅡtype, and 13 cases with HaraguchiⅢtype. The patients who were HaraguchiⅠand Haraguchi Ⅲtypes accepted the operation with posterolateral approach. The patients who were HaraguchiⅡtype and combined medial malleolus fracture accepted the operation with medial approach. The HaraguchiⅡpatients who were not combined medial malleolus fracture were used the medial paraachilles approach. Images of the ankle joint were filmed 2 weeks, 4 weeks, 12 weeks, 6 months and 12 months after the surgery. The healing time, complications and corresponding record outcome were determined by X-ray and clinical examination. At the last follow-up, ankle function and quality of life of patients were evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and SF-36. Results Eighty-three patients were follow-up for 6-24 (mean 15.4± 6.2) months. The fractures healed on X-ray. The average X-ray healing time was from 12 to 24 (mean 18.6±4.2) weeks. AOFAS score was 71 to 100 (mean 88.4±8.4) points. Sixty-seven cases were excellent, 14 cases were good, 2 cases were moderate, and good rate was 97.59%. SF-36 physiological score was 31.6-69.2 points(mean 48.4 ± 4.8 points);SF-36 psychological score 28.6-64.5 points(mean 45.8 ± 3.5 points). Chronic ankle pain was complained by one patient. He was diagnosed traumatic arthritis, oral non-steroidal drugs was used to relief his ankle pain. One patient wound infected, and healed after treatment. No instrument failure and fracture displacement were found. Conclusion According to fracture morphology and clinical features after posterior malleolar ankle fracture, different surgical approaches are selected, which will be satisfied with the outcome.

8.Advance in genetic research on multiple system atrophy.
Chinese Journal of Medical Genetics 2015;32(3):418-421
Multiple system atrophy (MSA) is a progressive neurodegenerative disorder. Widespread presence of glial cytoplasmic inclusions is the neuropathologic hallmark of MSA. The disease has long been considered as a sporadic disorder. However, in recent years, a few familial cases of MSA have been reported, and researches have verified certain genetic variants could increase the risk of MSA. These indicated genetic factors may play an imported role in the pathogenesis of MSA. In this review, the emerging evidence in favor of genetic players in MSA is discussed.

Objective To invastigate the effect of living donor liver transplantation(LDLT) with middle hepatic vein(MHV) and LDLT without MHV on the donor. Methods Between August 2007and August 2008, 62 LDLT were performed, 30 LDLT with MHV (group A), 32 LDLT without MHV (group B). Before operation, comprehensive assessment the graft size, remnant liver volume (RLV), fatty liver, MHV type, and the level of portal hypertension in recipient to determine whether harvested MHV. The graft was harvested depending on the port vein and hepatic artery ischemia-line,ultrasound was used to definite the branch of MHV. The donor operative time, intraoperative blood loss, postoperative hospital stay, bilirubin, INR, ALT, albumin, and complications were recorded in detail. Results Operative time, blood loss, hospital stay between group A and group B were not significant difference. But the bilirubin, INR, ALT in group A was higher than group B; Albumin recovered slower and with more ascites in group A. The early complications post-operation were similar in the two groups. There were 2 cases with wound infection in group A and 3 in group B. 3 cases complicated with cholestasis in group A and 1 case in group B, all of them gradually recovered to normal after 2 weeks. 2 cases occurred cross-section bile leakage in either group, the patients administrated with anti-infection, external drainage and recovered;4-7 days after operation, there were 6 cases in group A and 5 cases in group B occurred delayed gastric emptying, it was alleviated after adjust diet, encouraging activities and administrated with gastrointestinal motility drugs. Conclusion Right graft with the middle hepatic vein may lead donor recovery delayed, but with precise evaluation, especially MHV type, remnant liver volume (RLV%)>30%, preserve the drainage of V4b and the artery segment Ⅳ,it's can ensure the donor's safety.
